ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 665,587, dated January8, 1901- Application filed July 7, 1900.

To all whom it may concern:

Be it known that 1, JAMES TANNEHILL, a citizen of the United States,residing at Walnut Grove, in the county of McDonough and State ofIllinois, have invented certain new and useful Improvements inAttachments for Corn-Planters; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to a cultivator attachment for corn-planters, andhas for its object to provide astroug, simple, and efficient cultivatorattachment applicable to all wellknown corn-planters and combiningtherewith novel means for raising or depressing the cultivator-disks.

My invention consists, further, of the combination, with the cultivatorand its means of attachment to a corn-planter, of a marker having adetachable and adjustable connection therewith.

The invention further consists in the provision of certain details ofconstruction hereinafter more particularly described in thespecification and pointed out in the appended claims.

In order that the invention may be more fully understood, reference ishad to the accompanying drawing, in which the figure represents a sideelevation of a corn-planter having my improved cultivator attachmentattached thereto.

In the present invention I have aimed to construct for corn-planters acultivator attachment which is composed of suitable parts applicable toall wellknown planters and arranged to be carried by the rear frame partthereof, that the cultivator-disks may follow in the wake of thecorn-planter wheels.

The object I have in view with the appliance such as I shall hereinaftermore fully describe in detail is to provide for a cornplanter acultivator attachment composed of suitable frame parts andcultivator-disks arranged for vertical adjustment and to travel in thewake of the wheels to cut out and destroy any and all Weeds and grasswhich may be growing in the path of travel of the planter-wheels. Theaction of the cultivatordisks will form a ridge over the row of corn,

Serial No. 22,861. \NO model.)

so as to keep water from settling in the row, preventing any washing outor flooding of the corn, which will prevent the ground from baking overthe corn, 2. further result being in covering all the corn which theplanterwheels fail to cover. With the application a of such a devicetime is saved byaccomplishing with one trip over the field what is usu-6o ally accomplished by a separate trip with a cultivator. With thisdevice I have provided, as above set forth, a marker combining in itsconstruction and application with the cultivator a novel marker, whichmakes the application of the cultivator desirable because of sucharrangement, the same being adjustable in connection with the cultivatorand coupled in such a manner as to permit the same to be raised orlowered.

In the following description it will be observed that I have referred tothe necessary parts commonto all machines and then to the partscomprising the cultivator attachment upon which I desire protection.

In the drawing, A refers. generally to a rectangular frame-support, towhich is suitably attached the main frame B of the planter, and 0represents the ordinary planterwheels journaled on the short axles 0,carried in a suitable manner by the frame B.

D refers to the planter-shanks carried forward of the planter, joined bythe angle frame supports d d, to which the frame B is attached,completing the machine-frame, and above the shanks D and connectingtherewith are carried the usual seed-hoppers d, as shown.

The usual drivers seatE is shown supported by the machine-frame in theordinary manner.

The above-described parts constitute the main elements of acorn-planter, with a few additional details, and I will now proceed todescribe in detail the cultivator attachment upon which I make claim.

To the rearof the center of the machine and at a point adjacent to theperipheral face of the planter-wheels C and below the center of the sameI have shown a hollow rock-shaft F, extending transverselyacross themachine, which is journaled in the depending frame- IOO supports f,shown having a vertical adjusting relation on the machine-frame B of theplanter.

G represents cu1tivator-disks,a pair of which are located and arrangedin such a manner as to travel in the wake of the planter-wheels O, asshown. Theseare shown having the short hub or journal extensions g, thatthe same may have an adjustable connection with the spindles g, whichare supported by the rockshaft F, this method of supporting the disksproviding a means of adjusting the same to desired angles.

A simple means is shown employed for actuating the rock-shaft F, thatthe cultivatordisks may be simultaneously raised or depressed, as isdesired, which may be further attained through the provision of thebrackets f, in which the-rock-shaft is journaled, which is capable ofvertical adjustment on the machine-frame, as shown. This I accom plishby the provision of a hand-lever H, shown rigidly secured or fixed atone end to the rock-shaft F, provided with the usual thumb, latch, rod,and sliding pawl arranged to engage with a segmental 'rack I, attachedat one end to the machine-frame, whereby the lever may be engaged atsuitable points in its throw for holding the disks at desired 1 pointsin their adjustment.

end of the rack is left free.

ing the same. vided a very novel means of attaching and adjusting themarker, which consists in the provision of a telescoping rod or bar J,capable of being telescoped into either end of the rock-shaft andcarries on its outer end the ordinary marker j, which may be held inalinement by the use of the ordinary cord j, which is held by a loopwhich at its opposite end is attached to a suitable hook on theseeder-hopper. The bar or rod J is provided at a suitable point in itslength with a knuckle-joint K, as shown, which permits of the outer endbeing raised or loweredor to give to the rise and fall of the ground asthe marker travels over the same.

It will be noticed in the provision of a cultivator attachment such as Ihave shown, illustrated, and described that the same is capable ofattachment to all ordinary planters now in use, and ample provisionismade for the use of a marker, which makes it all that isdesired by theuse of a cultivator attachment for cornplanters.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is-

1. A cultivator attachment for corn-planters, comprising a rock-shaftjournaled in vertically-adjustable brackets to the planterframe,cultivator-disks supported by the rock-shaft and arranged to travel, apair of each in the wake of the planter-wheels, the mechanism foractuating the rock-shaft to raise or depress the disks and means wherebythe angles may be changed as desired, substantially as described.

2. An attachment for corn-planters, comprising a hollow rock-shaftsupported in vertically-adjustable journals detachably secured to theplanter-frame, cultivator-disks supported, a pair at each end by therockshaft to travel in the wake of the planterwheels, the combinationtherewith, of a marker secured to a telescoping rod with the hollowrock-shaft, means for raising the disks and means for raising the outerend of the marker, all substantially as described and shown.

3. In a corn-planter attachment, the combination of a hollow rock-shaftsupported transversely at the rear of the planter in brackets dependingfrom the planter-frame, cultivator-disks adjustable to suitable anglesand height traveling in the wake of the plantor-wheels, a rod or barcapable of being tel- Referring to the segmental rack I, it will be inoticed that the rack is pivoted at its rear end to an upright supportI, attached to the frame Bin any suitable manner, and the outer f Thisprovision 1 will permit the rack to have a swinging movei ment whichwill permit it to adjust itself when the rock-shaft is adjusted byreason of i a raising or lowering of the brackets support- In thisconnection I have proescoped into either end of said rock-shaft andcarrying a marker on its outer end, and provided with a knuckle-jointintermediate its length, all arranged and operating substantially in themanner and for the purpose described.

4. The combination with a cornplanter, of a cultivator attachment andmarker comprising the hollow rock-shaft F, journaled in thevertically-adjustable supports f, cultivatordisks G, a pair located atopposite sides of the planter in the Wake of the planter-wheels,supported by the rock-shaft and arranged to be adjusted to suitableangles, the means for actuating the rock-shaft for the purposedescribed, the telescoping rod J, provided with the markerj, theknuckle-joint K, at a suitable point in the telescoping rod to permitthe outer end to rise or lower, all substantially as described.

5. An attachment for corn-planters, com-- prising a hollow rock-shaftsupported in vertically-adj ustable brackets to the planterframe,cultivator-disks supported by the rockshaft, a hand-lever attached tosaid rockshaft and provided with means for engaging a segmental rackattached to the machine, the same having a pivotal bearing relation witha suitable support whereby the same will adjust itself automatically tothe adjust ment of the vertically-adjustable brackets supporting therock-shaft, substantially as described.

In witness whereof I affix my signature in presence of two witnesses.
